Introduction

Developing against Jetty APIs for either embedded or closely integrated purposes. This style of development requires Jetty jars on the class path during development and runtime.

Developing standard web applications that use only standard APIs, but that are deployed in Jetty either for development and/or production. These web applications might use some Jetty APIs, but only as normal WEB-INF/lib libraries.

Developing against Jetty APIs

Developing against the Jetty API lets you develop both standard web applications and embedded web applications. The basic approach is to install the required Jetty Jars and dependencies on your class path and then write and run a variation of one of the examples in the Embedding Jetty Tutorial.

Standard Web Application Development

To develop a standard web application with Jetty, typically you need only the servlet.jar on the classpath of your IDE and then some way to run a Jetty server just to test the web application as part of a normal development lifecycle:

Jetty Maven Plugin

Apache Maven is a software project management and comprehension tool. Based on the concept of a project object model (POM), Maven can manage a project's build, reporting and documentation from a central piece of information. It is an ideal tool to build a web application project, and such projects can use the Jetty/Feature/Jetty Maven Plugin to run the web application in development mode.

Typically a build tool needs to assemble a web application into a war file, which merges the compiled code, the static content and the deployment descriptor into a zipped file, which can then be deployed in a server. However, during development, the time it takes to assemble a war file can be significant, and the resulting bundle can be hard to develop against as source code changes are not immediately reflected.

This runs the application directly from its unassembled source components, so that if static content is saved from your IDE's editor, it is immediately visible to the Jetty server. If you save a java class, then your IDE will probably compile it on the fly and the plugin will notice the change and redeploy the web application within seconds.

Ant Jetty Plugin

The Jetty Ant plugin provides an ant target that allows a jetty server to be run from an ant build.xml file.

OSGi Plugin

Eclipse Web Tooling

Embedded Jetty Main

A short Java Main can be written to launch your web applications in Jetty directly from your IDE, just as you would run any other Java application. This allows your IDE's debugger to step through both your application and the server code, and thus allows very integrated debugging.

See the Embedding Jetty Tutorial for examples of running a webapp from a main. See the sections below for how to setup your IDE to run embedded jetty.
